I started by solving this for myself. Then sold it as a service. Now I'm turning it into a product.
A few years ago I was running my own projects and needed to post consistently across platforms.
I tried Buffer. Hootsuite. Later API, Zapier native integrations.
None of them did what I actually needed: take content from my workflow and publish it programmatically, without logging into a dashboard, without manual steps, without another subscription UI I had to learn.
I've been automating a lot of things with n8n. But social media always had one missing piece there was no reliable API to actually publish across platforms without OAuth nightmares and rate limit roulette.
DOHOO fixes that. One clean API endpoint. You send content, specify platforms, done.
